17 Claims. (Cl. 112-21) This invention relates, as indicated, to signature stitching machines and the like, and more particularly to a compact and eiiicient delivery for collecting the stitched assemblies discharged from such machines.

The invention, while not limited thereto, is concerned principally with signature stitching machines of the saddle type, wherein the stitched assemblies are ejected by being displaced beyond the discharge end of the saddle, and has for a primary object the provision of a delivery mechanism adapted to receive the assemblies thus discharged and automatically-to transfer them to a convenient collection point from which they may be readily removed for further handling. It is also an object of my invention to provide such a delivery mechanism in- :luding a belt conveyor and transfer means operative in timed relation with operation of the stitching machine to deposit the signature assemblies asdischarged flatwise upon the convevor. Another object of my invention is to provide a delivery mechanism including a belt conveyor and transfer means of this nature wherein the conveyor advances in response to operation of the transfer means. It is an additional object of my invention to provide means for adjusting the thus responsive advance of such belt conveyor. Otherobjects and .advantages will1 become apparent. as the following description procee s.

Tothe accomplishment of the foregoing and related ends the invention, then, consists of the means hereinalfter fully described and particularly pointed-out in the c alms.

The annexed drawings and the following description set forth in detailcertain mechanismsl embodyingfthe invention, such disclosed means constituting, however, but one of Various mechanical forms in which the `principle of the invention may be used.

In said annexed drawings:

Fig. l is a front elevation of my delivery-mechanism shown in operative association with a `signaturestitchice tion to movement of 'such heads. Actuation of the anvil members is controlled by means of vertical member 9 provided at its lower extremity with a cam 10 which is cooperable with a camming disc 11 keyed on the transverse shaft. chine is also driven by the shaft 6 through a connection to end face 12 of the camming disc of a link 13 by means of a pin 14. Connected to the other end of the link 13 is a lever 15 pivotally connected at one end to the frame of the apparatus and having a feed slide block Y 16 secured to its free end. It will be apparent that the link 13 will operate to reciprocate the feed block longitudinally of the saddle. The feed block 16 has attached thereto an elongated bar 17 located within and extending tion of the feed block. This elongated bar is provided with a feed nger 18 which projects laterallythrough ak fingers are spaced apart a predetermined distance such that the ejector tinger 19 will be in a position to engage an assembly at the stitching station when the feed finger :18 is located adjacent the saddle stop 2. This positiony ing of the fingers will ordinarilyoccur at the limit of the reverse movement of thefeed block 16, and atfthe limit of forward movement, the feed nger will occupy,

the position adjacent the stitching station while the ejec- :tor finger will be moved to a point beyond the saddle discharge end.

In the operationof the stitching machine thus far` described,.an assembled signature .placedon the saddle 1 will be automatically moved by the feed finger 18 to the stitching station and the stitching heads andanvil ing machine of the type with which it is designed to opy erate;

Fig. 2 is an end elevation of the .apparatus shown in Fig. l as viewed fromthe left thereof;

Fig. 3 is a partial end view of the apparatus illustrating parts of the delivery mechanism in a different operative position;

Fig. 4 is a vertical section taken on the plane of the line 4 4 in Fig. l;

Fig. 5 is a top plan view of the delivery mechanism.

Referring now to the drawings, and especially to Fig. l, my improved delivery mechanism is there shown in combination with a saddle stitcher, both the delivery mechanism A and the stitching machine proper B being supported upon a common base portion C. The stitching machine comprises a saddle 1 of general inverted-V cross-section, upon which the assembled signatures are placed by the operator of the machine adjacent the adjustable stop 2 thereon, and stitching heads 3,' two in number being shown, adjacent the discharge end of the saddle. These stitching heads, mounted upon a vertical supporting member 4, are 'of conventional construction and need not therefore be described in detail. An electric-motor 5 housed within the base portion C operates the stitching heads through suitable connections (not shown) and drives the transverse shaft 6 through a worm and worm gear assembly 7.

AAssociated with each stitching head -3 is a clincher lbar or anvil member 8 which is reciprocated in opposimembers will then operate to stitch the assembly. While this assembly is being stitched, the feed member 16 and.

hence ythe fingers 18 and 19 will be withdrawn with the finger 19 sliding by the assembly at the stitching station andcoming to rest in a position in engagement therewith at the same time that the feed finger slides by and is positioned to engage a second assembly placed on the saddle. Upon the next forward motion of the feed slide the ejector finger will move the now stitched assembly beyond the saddle discharge end and the finger 18 will locate the second assembly in stitching position. y

The feed cycle is, of course, controlled in timed relation to the `operation of the stitching head throughthe linkage 13, 15, and in this manner they machine is ca, ,pable of continuous automatic operation.

Located adjacent the discharge end of the saddle is the delivery mechanism A comprising a normally vertical transfer plate 20 which in this position is aligned with the stitching machine saddle and is adapted to have` .the stitched signatures placed thereon by the ejector finger 19. The plate may be provided with an adjustable stop 21 to limit such movement of the signatures, and a` curved guide plate 22 may be utilized to partially compress the signature assemblies as they move onto the plate. Pivotally connected at 23 to the respective sides of the transfer plate are the arms 24 which are connected at their other ends to crank arms 25 fxedly attached 'to a transverse drive shaft 26. A further arm 27 is pivo'V tally connected to one side of the plate at point 28 below the pivotal connections 23. Such further arm is also pivotally connected to the supporting frame 29 of l the delivery mechanism and cooperates with the arms 24 to translate the transfer plate 20 in a manner hereinafter described.

Frame 29 projects forwardly from the stitching machine, as shown, and may be supported at its outer yextremity bymeans of a diagonal brace 30. The frame houses and supports a generally horizontal conveyor 31 which is of the endless belt type and is provided with a drive roller 32 at its inner end and a guide roller 33 at 5 its outer limit. The drive roller 32 is. mounted on a shaft 34 supported by the frame side brackets 35, while the guide roller 33 is mounted on a shaft 36 supported by adjustable bracket members 37 Ilikewise attached to 4,the frame sides.
